Ashamed of having acted rashly,he apologized to Jack.
问题描述：
Ashamed of having acted rashly,he apologized to Jack.
请问这里本来是 He was ashamed that he had acted rashly .So he apologized to Jack.
那个having 来自于过去完成时态的的 had,对不.
-_-!
答
be ashamed that+从句
be ashamed of (doing) sth.
是因为动词词组的变化,使had done变成了having done.
另,此句中另一语法点是因果复合句变成了其中一个做伴随的成分,句首省略了Being...
